this is where you come in myke lol. i popped out all the old bearings and took off the old hubs. now when i install the new bearings, i just grease the shit out of them then put them in right? and there was a lot of grease inside the rotor where the bearings go, do i fill this back up with grease, or are the bearings the only thing that get greased? and what kind of grease should i use?
